Description

technical field [0001] The invention relates to a motor for a barrier gate, in particular to a DC motor for preventing a backlog of carbon powder for a barrier gate. Background technique [0002] The motor for the barrier gate realizes the opening and closing of the barrier gate through the forward and reverse rotation of the rotor. The rotor is equipped with a commutator. , The side of the commutator away from the iron core will deposit carbon powder, and there will be short circuits between the commutator segments and between the commutator and nearby parts. Contents of the invention [0003] The purpose of the present invention is to provide a method that can clean the carbon powder on the commutator to avoid short circuit between commutator segments, avoid short circuit between commutator and nearby parts, and prolong commutation. Anti-toner backlog DC motor for barrier gates with long service life. [0004] In order to achieve the above object, the present invention...
